Analog electronic timepiece having a multifunctional calendar disc

An electronic analog timepiece for displaying time by means of hands driven by a motor M.sub.1, and also displaying at least two other items of time information by means of a second display having a disc, an indicator and a reversible stepping motor M.sub.2 for moving one of said disk and indicator relative to the other, said timepiece comprising:

• a time-keeping circuit producing a first signal for driving said motor M.sub.1 to display the time, said time-keeping circuit also producing a daily signal S.sub.J once each day;
• a manually actuated exterior control means for selecting a category of time information to be displayed;
• an interpretation circuit responsive to manipulations of the control means for producing a signal S.sub.K representing the selected category of time information;
• and,
• a perpetual calendar management circuit comprising,
• a plurality of calendar counters responsive to said daily signal S.sub.J,
• a multiplexer connected to said calendar counters and responsive to said signal S.sub.K for producing an order signal S.sub.C representative of the ranking of an item of information being displayed on said second display,
• a reversible counter for producing a disc signal S.sub.D representing a current position of one of said disc and said indicator, and,
• a comparator-subtractor responsive to said order signal S.sub.C and said disc signal S.sub.D for applying a recurring signal S.sub.R to said reversible motor M.sub.2 and said reversible counter until said disc signal S.sub.D is equal to said order signal S.sub.C, said recurring signal S.sub.R incrementing a count in said reversible counter and stepping said reversible motor M.sub.2 in a first direction when S.sub.D >S.sub.C and decrementing a count in said reversible counter and stepping said reversible motor M.sub.2 in a second direction when S.sub.D <S.sub.C,
• said disc having thereon a plurality of distinct zones corresponding to a plurality of categories of time information, each zone having therein a plurality of symbols representing items of time information, the symbols of said zones occupying successive rankings on said disc and the symbols in each zone being different.
